Fig. 8 is afdetail `of arspoke;

Preferably, the Wheel. 'is provided 4JVith spokes extending substantially 'on a tangent y tothe periphery ofthe' hub flange veachlset of spokes being crossed j as is thel genral..

practice and preferably the riml 1 is provided with a circumferential. groove A2 vas shown in Fig., 4 or With grooves 3 and 4 as In the construction here,

shown the rim is provided-With a demounti able tire carrying` rim 5A and this rim may be ofl any desired type.. Preferably, `the .Wheel rim 1 is provided with an upturned l fiange 6 on the inner side against which an upturned portion of the tire rim engages. Near the outer flange ofthe tire rim 5 and on the inner side ofthe Saidrim -is provided an annular r-ib 7 and the outer side receive thespokes 9 and this aperture is of a size to permit the inner headed end 10 of the. spoke-to pass therethrough, the shank 11 of the T head portion being substantially of the same'diaineter as the headed end 10.

The spoke is inserted through the aperture 'at the rim and when so inserted the shank 11 rests in and practically fills the aperture therefor While the cross portion 12 of the T head lies in the groove with the longitudinal axis thereof in the plane of the groove. This threaded with right hand threads 15 as' T head riding in the groove as for instance 1 for use on the front Wheel of an automobile `or such Wheels as are not driving Wheel'sojf a. vehicle. This hub 1s raient N0. 1,119,403, ofv Dec. 1, 1914, and involves the flanged portion 13 and a fianged portion 14, the' cylindrical parts of which are substantially in telescopic rela# tion as shown. The portion 13 is internally shown while the portion 14 has a left hand threaded part-,16. As is'shoWn in Fig. 3, tle portion 14 has a. keyway 17 provided larly provided with a key\ vay 19 in whichv a key 20 may be positioned as shown in F ig. 2. ln threaded engagement with these two lthreaded portions 15 and 1G is a cylindrical adjusting member 21 having corresponding threads at each end for the respective hub rot-ation of this adjusting member 21 having @portions and this member 2l is shaped to carry the'bearing rings of the anti-friction bearings as will be understood from Fig. 2. The spindle 22 of the axle is supported by these bearings and the member' 21 is therefor revoluble on this spindle. lDue to the fact that` the two flanged hub members- 13 and 14 are secured to the rim. by means of spokes as hereinafter more fully described, they ,are held from rotation and therefore lthe right and left 'hand threaded relationship with the respective hub members causes the said hub members to move in one di rection or the other longitudinally of the aXis of the hub7 it beingv understood that the keys are of' a character to be removed to permit rotation of' the adjusting member 21` `each provided with a cylindrical part 24 Which is notched as indicated at 25 into which notches the spoke ends may be inserted with the heads 10 in the interior of the cylindrical portion as will be understood from Fig. 2.

nite similar in con!L struction to that shown 1n myformer U. S;

' a notched hub When the wheel is tobe assembled the two i hubportions 13 and 14l by turning of the `member 21 are brought closely together and the spokes are inserted through the rimaperture as before stated and the inner ends 'positioned in the. slots provided in the respective hub members, there `being a set of spokes for each hub member, the spokes of said sets being-in alternate relation at the rim. Vhen the spokes have been positioned with the inner ends in the respective'hub members, rotation of theadjusting meniber 21 causes the said members/13 and 14 to move in opposite directions longitudinally of' the axis' of the hub causing uniform tension onthe spokes'and forcing the rim to occupy a plane:centrally between the two hub members. vAfter .the spokes have been drawn sufficiently taut the key 18 may be inserted and a cap 26 positioned over theouter end as shown in Fig. 2 enclosing the therein for a key 18 and the part 13 is simihub end.

i In the form. of construction shown in Fig. 4 both sets. of spokesv from each hub flange are connected substantially to the center plane of the wheel rirh but, by means of' the construction shown in Fig. 5 lfor instance, the sets of spokes may extend to a groove for each set and the wires extending from one side of the Wheel flange may extendlto the opposite `side of the Wheel rim and thus be vcrossed if desired. In fact any character ofl Wheel lacing may be employed in this construction as may be found desirab-le, either ay straight spoke ora spokeextendingto a tangent as shown, the requirement being that a seat in the rim should be provided for the T heads of t-he spokes and rovided to receive the opposite ends of t e spokes.

` In the construction shown in Fig. 6 the same result is achieved as in the construction shown. in Fig. 2. The construction in Fig. 6, however, is best adapted for use on the .driving wheel of automotive vehicles. With such driving wheels is employed a` brake drum 30 which is keyed to the spindle of the axle. The flange 32 for the spokes at the inner end of the hub member may be bolted to a Hange of the hub member 31 land preferably this hub member is provided with an extending substantially rectangular member 33 and both the spoke flange 32 and the disc of the brake drum 30 should be apertured to engage over this rectangular port-ion 33 so that the strainincidental toapplication of the brake or to the normal driving of the wheel is not applied directly to the bolts 84 for holding the members in assembled relation.

Where a brake drum is to be used, it is evident that the flange or portion of the here shown) to beapplied to the drum. Therefore, in order to apply the construction ot theright and left hand threaded adjusting member, I provide the outer end'of the member 31 with a right hand threaded por' `fact that lthe hub end 36 is held from rotation through the connection of the kspokes therewith, rotation of the adjusting member due to the right and left hand threaded construction described carries the member 36 inwardly or outwardly longitudinallyof the axis of the hubl to loosen'or tighten the spokes.- This member 35 is to be and preerablymay be keyed to the inner hub memberBl in the same'manner as desrribed relative to the key relationship of the hubmember and adjusting member of 2. By this latter construction the principle of operation of the device is `secured as is the -case in Fig. 2 and the loosening or tightening of the spoke does not alter the relationship of the brake drum in its position relative to the brake band that is to be understood as being p0- sitioned thereabout.

By the Aconstruction described a wheel 'that is neat in appearance and simple in construction is secured and that is readily repaired in case of the breakage of al spokeor of the bending of the rim from normal position inasmuch as even though' the rim might be accidentally bent and spokes broken the hub may be collapsed and the broken spokes'removed and new ones insert ed and upon expanding the hub member to tighten 'the spokes the wheel'rim will be forced to assume its normal cylindrical postion, due to the uniform tension being placed upon the spokes.

Having thus briefly described my invention, its. utility and Inode of operation, what l claim and desire to secure by Letters Pat u ent of the United States is l.
